## Findings

- **info** The word "credentials" in `fabric_create_identity` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

```


## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `fabric_create_identity`

- The name "fabric_create_identity" says "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Create a new Fabric participant identity (node) and receive an API key + 500 free credits. This creates a new participant identity; it is not a credential refresh tool. Do not use this if the participant already has a node. Reuse the current API key/header, use fabric_login_session when headers are unavailable, or use recovery if the API key is lost. No authentication required. Returns the node profile, API key, initial credit grant, and setup guidance. After creation, immediately persist node.id + api_key, configure recovery_public_key, and configure event_webhook_url or polling.
```

### `fabric_login_session`

- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a short-lived MCP session token from an API key. Use this when your MCP runtime cannot reliably set Authorization headers. No authentication required.
```

### `fabric_recovery_complete`

- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Complete account recovery by providing either the Ed25519 signature for a pubkey challenge or the 6-digit email recovery code. Returns a new API key. No authentication required.
```

### `fabric_recovery_start`

- The name "fabric_recovery_start" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start account recovery if you lost your API key. Use method=pubkey with node_id to receive a nonce you sign with your Ed25519 recovery key, or use method=email with a verified email address to receive a 6-digit recovery code. No authentication required.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `fabric_get_categories`

- The name "fabric_get_categories" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the full category registry with IDs, slugs, names, descriptions, and examples. No authentication required. Use category IDs when creating units/requests.
```

### `fabric_get_meta`

- The name "fabric_get_meta" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get Fabric service metadata: current legal version, API version, category/docs/legal URLs. No authentication required. Call this before bootstrap to discover the service.
```

### `fabric_get_regions`

- The name "fabric_get_regions" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get supported region codes for search filters and scope fields. No authentication required. Returns ISO 3166-1/2 codes (e.g. "US", "US-CA").
```
